Answer: B. $7739.05=5500(1.05)^t$

Step-by-step explanation:

The formula to find the compound amount (compounded yearly):-

$A=P(1+r)^t$ , where P is the principal amount invested, is the rate of interest and t is time period.

As per given , we have

P=$5500 , r=5% = 0.05 and A = $7,739.05.

Substitute all the values in the formula , we get

$7739.05=5500(1+0.05)^t$

$7739.05=5500(1.05)^t$

Hence, the equation describes Meredith's investment based on t, the number of years she kept the account open : $7739.05=5500(1.05)^t$
